Study of the low-order $\Delta \nu$-$\bar{\rho }$ relation for moderately-rotating $\delta$ Scuti stars and its impact on their characterisation

Julio E. Rodríguez-Martín, Antonio García Hernández, Juan Carlos Suárez +1

The large separation in the low radial order regime is considered as a highly valuable observable to derive mean densities of $\delta$ Scuti stars, due to its independence with rotation…
